The U.S. House of Representatives election in Delaware was on November 8, 2022. Voters elected one candidate to serve in the U.S. House from the state's one at-large U.S. House district. The primary was scheduled for September 13, 2022. The filing deadline was July 12, 2022. Since only one Republican candidate filed by the deadline, no primary election was required. Lee Murphy (R) advanced to the general election.

Candidate filing deadline	Primary election	General election
July 12, 2022	September 13, 2022	November 8, 2022

Heading into the election, the incumbent was Lisa Blunt Rochester (Democratic), who was first elected in 2016.

A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Delaware utilizes a closed primary process, in which the selection of a party's candidates in an election is limited to registered party members.

For information about which offices are nominated via primary election, see this article.

This page focuses on Delaware's Republican primary for the U.S. House. For more in-depth information on the state's Democratic primary and the general election, see the following pages:

Post-filing deadline analysis

The following analysis covers all U.S. House districts up for election in Delaware in 2022. Information below was calculated on August 30, 2022, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.

Two candidates filed to run for Delaware's At-Large U.S. House district, one Democrat and one Republican.

The two candidates who ran this year were one fewer than the three candidates who ran in 2020 and 2018, and five fewer than the seven who ran in 2016, when the seat was last open. Two candidates ran in 2014 and three did in 2012.

Because it only had one U.S. House seat, Delaware did not need to redistrict after the 2020 census.

Incumbent Lisa Blunt Rochester (D), first elected in 2016, ran for re-election. Lee Murphy (R) was the only Republican candidate who filed to run. Blunt Rochester and Murphy were the Democratic and Republican nominees in 2020 as well.

Since the two candidates who filed were from different parties, there were no contested primaries this year. The Republican primary was contested in 2020, 2018, and 2012, while the Democratic primary was contested in 2016. There were no contested primaries in 2014.
